IMPROVEMENT IN GANG PLOW.

To ALL WHOM IT MAY CONCERN;

Be it known that 'I, FREDERICK P. SMITH, of Petaluma, in the State of California, have invented a certain new and useful Improvement on Gang-Plows; and I do hereby declare that the following is a full, clear, and exact'description of the same, reference being bad to the accompanying drawings, and to the letters and marks thereon, which saiddrawiugs form part of this specification, and represent a plow constructed under my inventionv Figure 1 being a side view, with the land or unbroken-soil wheel removed, and

v Figure 2 being a top view thereof. 7

In both of these figures, where like parts are shown, like marks and letters are used to indicate the parts.

In this plow, the axle a of the furrow-wheel b is permanently attached to the beam 0. The axle d of the land or unbroken-soil wheel e is attached to the bars f, on the end of the beam, by nuts and bolts 9, the slot or space it in or between the bars f allowing of the vertical adjustment of the axle d to adapt the wheel to the land or ground being traversed over. The forked arm 2', which holds the caster-wheel j at its upper end, has a similar means for adjustment by nuts and bolts It, and'the slots 1 of the bars m attached to the rear of the tongue of the plow.

The plows, 'rt op, are afiixed to the frame-bars q r s. A hole in the front end of these frame-bars allows the passing through of the rod t, for the suspension of the bars thereon, which rod passes through the bars u, aflixed to the beam 0, there being a space, a, between each set of the bars u, for theupward and downward movement of the ends of the bars. The movement of the bars, and the plows attached thereto, is strictly vertical, the rear and the front ends of the bars being operated at the same time and by the one motion of the hand-lever w. Each plow will therefore be raised or lowered to the same degree or extent. The rear ends of the bars are connected to the lever to by the rod a, lever y, shaft 2, segment or sector z,'and cord or chains 3 the shaft'z having hearings in the arms a, afiixed to the bars 20', the forward ends of which are aifixed to the top of the beam 0.

The front ends of the bars are connected to the lever why the shaft 11', which is attached to the lower end of the lever, and may be made of the same piece of metal, and as an extension of the lever, and the other devices ,shown by the drawings, viz, pulleys u on the shaft 1), cords or chains 15, and pulleys s. The shaft of the pulleys it has its hearings in the bars r which are attached to the beam '0, and the shaft of the pulleys s has its bearings in bars q attached to the lower part of the beam 0. The cords or chains t are afiixed to the rods 6, as shown by fig. 1, so that as those chains or cords are moved up or down, they give a like movement to the rod and the ends of the bars.

The lever to is near the drivers seat and it will he noticed that the frame and plows can at any moment be readily raised or lowered, and thus easily be adapted to the soil being plowed, and to the variations of the surface, as also to whatever obstructions may be in the track of the plow, while both the frame and the plows can be elevated to adapt the plow for travelling from one location to another, the usual curved toothed bar 0 being used to hold the lever inits desired position.

What I claim as my invention, and desire to secure by-Letters Patent, is-

1. The arrangement of the devices and means herein recited for raising and lowering the frame and plows.

2. The bars, with spaces on the end of the beam, and on the tongue, with the bolts and nuts for the adjustment of the land-wheel axle, and the caster-wheels arm, as herein set forth.

This specification signed, this 13th day of April, 1868.
